ADJUSTABLE HEAT AND FUEL ECONOIVIIZER.

Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed February 20, 1914. Serial No. 819,912.

1'0 My invention has relation to a heat and fuel economizer consisting of a series of united removable hollow sectlons having 1n- "ternal partitions or means forming baffles J for. the coursing air therethrough employed 16 as an 'conomizer in the use of fuel, in stoves,

ranges and furnaces, to increase from a given quantity of fuel the combustion of the free carbon released during the burning of such fuel, with attendant heat units to a greaterdegree conserved and utilized, as well as to an increased degree the gases ordinarily passing off unburnt or unconsumed into the chimney conserved and advantageousiy utilized in the combustion chamber of the range, stove or furnace, 1n cooking, baking, house-heating, power purposes, etc.

Under the foregoing defined relation of my invention, it therefore consists, generally stated, in an" economizer provided in sectional form, assembled, yet the members readily separated when necessary, and permitting of such 'a grouping of sections or members as to accommodate the economizer appliance to the varying forces of draft currents as found indifferent stoves, ranges and furnaces, those of the same make and size and often under apparently similar conditions'being-foundto have strikingly differentdraft force.

My invention further consists of an appliance, composed of a series of hollow sectional air and as tight united members partitioned-or baf fled internally from the inlet member to the outlet member arranged with alley-ways and the said partitioning 0r baffling arranged to prolong or retard the free passage of air ther'ethrough so as to cause the same in taking circuitous paths of escape to become gradually increasingly heated to the alley-Ways through whichdischarged over the inflamed mass of the combustion chamber and which air so superheated'in the one instance is taken from the ovenof the stove or range and in the other inits course'is acted upon by the inflamed precisely the same in general arrangement,

may be attached either to the inside of the fuel door, or to the inside of any convenient portion of thefurnace surrounding the combustion chamber, having its inlet arranged to take air from the outside of the said fuel door or from the outside of any other portion of said furnace, and which air, so taken, is thus heated in its passage through the respective assembled sections of the appliance by heat from the inflamed mass of said cornbustion chamber for cooking, baking, heat ing, power or other purposes.

My invention further consists of an adjustable economizer appliance constructively arranged in substantially the manner hereinafter described and claimed.

The nature and scope of my present invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which- Figure l, is a perspective view ofa series of detached sectional hollow members constituting the adjustable economize-r appliance of my said invention arranged to be horizontally assembled and to be close to an internal member of the range, as the oven, and so as to be in direct communication with the upper part of the combustion chamber. Fig. 2, is a longitudinal section of a range, showing the economizer appliance ,of Fig. l, in application for actual use. Fig. 3, is a perspective view of a series of detached hollow members or sections partly broken away, the said members be ing arranged to be removably locked to each other in a vertical relationship, when assembled, and each provided with internal partitions forming baffling means for the coursing air in its passage therethrough for being superheated and the said hollow members soarranged as that narrow vertical channelways are formed in the grouping of the said members'or sections together, so as to permit the inflamed mass of the combustion chamber to impart its heat to the 'inbetween walls of the grouped sectional members and thereby to assist in the superheating of the air in its travel therein from the inlet member of the appliance to the outlet member openings or alley-Ways thereof, whereat the more or less highly superheated air is discharged into the inflamed fuel of the combustion chamber, to thus quickly and effectively assist in the consumption of the free carbon generated b the firing of the fuel in the said-combustion chamber' as well as to assist to a marked degree in consuming the gases that hitherto infurnaces, stoves or ranges have passed ordinarily to the chimney unconsumed and wasted; and Fig. 4, is a vertical longitudinal section of a furnace and the combustion chamber door shown closed and with an appliance embodying features of my invention in the form shown in Fig. 3, applied to the inner side of the said door and with the inlet extending sections or members are oblong with end openings a and with the opposite ends provided with hollow tenons a", to permit of snug fitting in an air and gas tight manner oneof the said members with each of the others constituting the said appliance a.

Internally of the series of sections or members a, are arranged irregular-shaped partitions a, consisting of oblique partitions as at a, cross partitions as at a and \I-shafped partitions as at a, all fully shown in Fig.1. These internal arrangements provide for baffling 'air in passage therethrough to the fourth or discharge member a, of Fig.1, wherein the partitions an and a", are arranged arch-like and beyond are arranged two series of oppositely inclined alley-ways a, and a, to-provide discharge outlets for the superheated bafiled air from the even a, of the stove or range and prior to the final discharge of the heats ed air from-the last of the said members directly above the combustion chamber inflamed mass of the stove or range, as clearly shown in Fig, 2, and thus as can be clearly.

understood, more or less hi'ghly heated in 7 its travel prior to being' freed through they said alley-ways a end a, to "effect consumption of the-free carbon given ofi by the fuel being burned-1 in the said-combusgreases tion chamber as well as largely reducing the.

proportion of unconsumed gases ordinarily passing to the chimney and wasted. There is thusfurnished by the use of an economizer 1n the manner as described a secondary supply of air superheated'continually deliverable directly above the inflamed mass of the combustion chamber to give a much greater quantity'of heat units as a result'' ant product from the consumed. fuel of the combustion chamber in a given time from a, given quantity of fuel consumed.

traneous conditions for the internal passing 7 air to be superheated by gradually'increas-r ing degrees in its course and prior to its discharge into the combustion chamber for the said defined objects or purposes.

With reference to Fig. 3, the series of sections or members of the adjustable apt pliance a, in this instance are arranged vertically as shown in Fig. 4, and'in apphcaition to the inner side of the furnace door I),

and with vertical narrow air channel-ways a provided between certain of them as so assembled, for permitting of the subjecting of such walls to the'direct influence of the heat-of the-inflamed mass of the combustion chamber, as clearly illustratedin Fig.

. 4, so asadditionally to superheat the baflied passing air, and by these -walls being maintained in such defined condition to thus in:

sure by such exposure of the air in its coursings to be heated to the very best possible conditions prior to its presentation to the products of the combustion chamber for utilizing the gases therein that otherwise more or less unconsumed as in the past" freely escaped into the chimney. The partitions of the respective assembled members int are shown in full and dotted outline in Fig;

3. The baifled air finally passing though the alley-ways a and a, is uniformly heated in its passage and is hottest at the point of discharge through the said alley-ways above the inflamed mass of the'combustion chamher and this secondary supply of air, superheated, presented thereto, in its coursing largely increases the ultimate derivedheat units of the productsof combustion of the pliance a, to the inner side of the'fuel door of the combustion chamber 6, detachably secured. thereto and having its inlet-tube a extending therethrough tothe outside there of. The temporary checking of the air in its passage and causing it to take circuitous paths due to the internal bafiling means pro-q vided therein as: described, enables thus a supply of ideallysuperheatecl air to'be provided all the time the furnace is in operation, for presentation over the combustion chamber mass thereof. By arranging the whatever the variable surroui'iding or otherconditio-ns may be, thus insuring perfect working of the appliance for supplying an ideal atmosphere for deriving economy in the burning of fuel, with increased heat products obtained from the standpoint of two important aspects, as hcreinbefore explained; that is, assurance of the combustion to a greater degree of the free carbon from the fuel of the combustion chamber, and second, a decided diminution in the quantity of gases ordinarily passing to the chimney unconsumed and Wasted, for the reason that such free carbon and such gasses by the arrangement of the appliance according' to my said invention in theuse thereof, as described, the secondary supply of air is heated to such a point as that its oxygen is at once rendered available for inducing desired combustion and this under a regulation practically always automatically con-' trollable by the internal working arrangement of the appliance and always suited to the requirements of the particular stove, range or furnace to which it is applied, because of its sectional features whiclnadapt it to any draft force or other special condition.

It will be manifestly obvious that the internal arrangement of the sectional members as described in the form as well as general shape of the partitions or battles of the several sections or members of the economizer may be varied, without departing from the spirit or real scope of my said invention; and hence I do not wish to be understood as limiting myself to the precise forms thereof, as illustrated in the accompanying drawings.

It will be observed that in both forms of the sectional members the second and third thereof are alike, while the first and fourth as shown, differ in internal arrangement from each other'and from the others from the fact that the first member is provided with the inlet-tube a, while the fourth member is provided with the series of outlet alley-ways a and a. The number of members like the second and third used, it will be understood in my economizer, may be increased or decreased according to the draft and general or other conditions of the stove,

'ange or furnace to be provided for.

l-laving thus described the nature and, objects of my invention, what I claim as new and desire to secure by Letters Patent is 5-- 1. In a heat and fuel economizer, the com bination substantially as described, of an intake section and additional sections, one of which is a discharge section, each of the sections having internal obstructions and the intake, the discharge andv the intermediate sections differing each from the other and the intermediate section being adapted to be combined with other intermediate sections of like fornror with'the intake and disc )2 rge sections alone, whereby the capacity of the economizer may be varied at will, substantially as set forth.

2. In an adjustable heat and fuel economizer, the combination, substantially as described, of an intake section having internal obstructions, a discharge section having internal obstructions and an intermediate section having internal obstruct-ions, differing each from the other, the intermediate section being adapted to be combined with other intermediate sections of like form or with the intake and discharge sections alone, whereby the. capacity of the economizer may be varied at will, for retarding variable draft conditions, and all of the sections, constituting the unit device alining in uniform relationship in their operative position, for the purposes as set forth.

In witness whereof, I have hereunto set my signature in the presence of the two subscribing witnesses.
